Which best describes an atom of carbon-13?
An atom of carbon with 6 protons and 7 neutrons.
Which best describes what happens a neutral atom becomes positive ion?
Cations.
What is the best description of Bohr model of the atom?
Each electron in an atom is in an orbital (*NOT* an orbit!!) at a specific energy level from the positive nucleus. The energy levels of these orbitals are fixed -- an electron can go from orbital 's' to orbital 'p', but it can't go halfway between these two orbitals. When an electron in an atom goes from a higher orbital to a lower one, then the atom must give off an amount of energy, that is exactly the difference in energy in the two levels. For a hydrogen atom, these orbital levels are fixed by the fact that the angular momentum of an electron in an orbital is quantized -- ie, it comes in exact multiples, but not fractions, of a minimal amount.
Which atomic model best explains the helium atom?
The quantum mechanical model best explains the helium atom. In this model, electrons occupy specific energy levels and exist in probabilistic electron clouds around the nucleus, rather than following fixed orbits. The helium atom has two electrons that exhibit both wave-like and particle-like behavior, occupying a region of space defined by their quantum states. This model accounts for the observed properties of helium, including its stability and the behavior of its electrons in interactions with other atoms.
Which best describes the beginning of the big bang?
A blowing of a balloon best describes the BIG BANG best
Why is the current atomic model calles electron cloud model?
The electron cloud model best describes the organization of electrons around the nucleus of an atom.
Why is the current atomic model called electron cloud model?
The electron cloud model best describes the organization of electrons around the nucleus of an atom.
What best describes Rutherford's model of an atom?
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
Why is the current atomic called the electron cloud models?
The electron cloud model best describes the organization of electrons around the nucleus of an atom.
Which best describes how an ionic forms?
One atom pulls an electron from another atom.
What hybridization best describes the circled atom in the molecule?
The circled atom in the molecule is best described by sp3 hybridization.
Which best describes an atom of carbon-13?
An atom of carbon with 6 protons and 7 neutrons.
Why is the current atomic model called the electron cloud model?
The current atomic model is called the electron cloud model because it describes electrons not as particles located at specific positions, but as existing within a cloud-like region around the nucleus, where they are most likely to be found. This model acknowledges the dual wave-particle nature of electrons and provides a more accurate representation of their behavior in an atom.
What best describes the nucleus of atom?
Nucleus is the centre of an atom and consists of positively charged protons and neutral neutrons.
Which best describes what happens a neutral atom becomes positive ion?
Cations.
What best describes ionic bonds?
Electrons are transferred from one atom to another.
What best describes the nucleus of an atom?
It’s the most massive part of the atom
